sys(16,0) would return the fullpath of exe (or application.servername).
If it's a mapped drive than wouldn't be sufficient. Then you could use WNetGetConnection :

declare integer WNetGetConnection in win32API ;
  string @ lpLocalName, ;
  string @ lpRemoteName,  ;
  integer @ lpnLength

lpLocalName = "z:" && drive letter
lpRemoteName = space(512)
lpnLength = 512


if WNetGetConnection(lpLocalName, @lpRemoteName, @lpnLength) = 0
 ? substr(lpRemoteName, 1, lpnLength)
endif
